Good Morning Tony,
I happen to be an ER physician and I think that fossa is cranial and near the nasal bone( it`s been many years since gross anatomy in med school LOL). What I mean regarding overtones are the additional notes and harmonies you hear following the intial note or tone particularly with the playing of chords. The Frankensteins sound much more like a live guitar in it`s ability to reproduce the blending of the mixture of notes and harmony. I`d been a user of push-pull amps for years prior to SET amps exposure. The PP amps were good at reproducing these overtones, hower the Frankensteins are just excellent in this regard and sounds much closer to what I hear live. My reference is live jazz in small clubs and most often unamplified. I don`t know if it`s due to the SET circuit, the use of DHT rather than pentode tubes, or having an interstage transformer in place of coupling capacitors. Probably all the above, I`m no engineer but something`s happening for the better. Any way I`m pleased that you`re enjoying these amplifiers already and your right they will continue to improve, what fun this hobby is.I agree with your opinion of Israel completely.
